- إجابة: C. Primary CNS lymphoma
- إجابة ثانية: B. Toxoplasmosis. multiple ring-enhancing lesions with edema
The HIV lecture separates the two by number of lesions: primary CNS lymphoma = solitary ring-enhancing lesion, while toxoplasmosis = multiple ring-enhancing lesions. The stem describes 'a ring enhancing mass' (single), which points to lymphoma. However, the CNS-infection lecture says that in an HIV patient (CD4 <200, toxo antibody positive) a mass is toxoplasmosis about 90% of the time. The stem gives neither the CD4 count nor serology, so both answers can be defended.

A
ليش غلط
In an HIV patient, the lecture's ring-enhancing brain lesions are primary CNS lymphoma (solitary) and cerebral toxoplasmosis (multiple). A Staphylococcus infection is not among the HIV-related causes it lists.

B
ليش صح
Disputed. Supported by the CNS-infection lecture: in an HIV patient with CD4 below 200 and a positive toxo antibody, a brain mass is toxoplasmosis about 90% of the time.

Disputed. Supported by the HIV lecture: primary CNS lymphoma gives a solitary ring-enhancing lesion, while toxoplasmosis gives multiple lesions; the stem describes a single mass.
